Abstract
We investigated the effects of hydrodebridement with pulsed lavage (HDPL) and negative pressure (NP) wound therapies, instead of excising the prosthetic graft, in patients with postoperative thoracic vascular graft infection (TVGI). Between 2020 and 2021, fiveTVGI patients aged 49.6 ± 19.4 years old underwent a combined therapy of HDPL and NP. The patients underwent a two-step procedure (firststep: re-sternotomy and HDPL; second step: NP) every 3 or 4 days. After negative tissue culture, the patients underwent omentum flap wrapping and skin closure. No hospital death was observed. The time to skin closure was 10.8 ± 3.4 days. The time to the day in which bacteria were not cultured was 3.5 ± 2.4 days. No recurrent infections occurred for 241 ± 186 postoperative days. Our strategy for TVGI patients may contribute to (1) sufficient infection control, (2) physical rehabilitation, and(3) less invasiveness for high-risk patients.
